Desmatosuchus spurensis

Desmatosuchus spurensis

Desmatosuchus was a heavily armored and particularly large variety of aetosaur. Its menacing shoulder-spikes were the most effective defense this hog-nosed herbivore had against large terrestrial predators like the pseudosuchian, Postosuchus. These armored plant-eaters likely traveled in herds, also for safety, as aetosaurs have been found in large monospecific deposits.
